A Study on the Constituents of the Fruits of Angelica gigas $M_{AKAI}$

참당귀 열매의 성분 연구

Silica gel column chromatography on the ether extract from the fruits of Angelica gigas $M_{AKAI}$ gave two kinds of crystalline constituents. The following derivatives of coumarins were identified by IR, NMR spectra, elemental analysis and physico-chemical tests: iso-imperatorin $(mp\;108{\sim}109^{\circ},\;C_{16}H_{14}O_4)$ and decursidin $(mp\;60{\sim}61^{\circ},\;C_{24}H_{26}O_7)$.
